IELTS Academic Task 1 Pie Chart Tips (2026)
Describe IELTS Academic Task 1 pie charts with share language, combined small slices, proportion vocabulary, and clear two-pie comparisons over time.
Use proportion vocabulary with accurate grammar
Core verbs include accounted for, made up, comprised, and represented. Noun phrases such as the largest proportion, a minority share, and an equal split also work well. Fractions can vary the style: roughly one third, just under a half, about one in ten. Switch between percentages and fractions only when both remain clear.
Watch subject-verb agreement and article use. Spending on food accounted for 20 percent is safer than Food were 20 percent. If two categories are equal, say they each made up the same proportion rather than forcing a false ranking.
Weak
Awkward wording
Food was 25% and transport was 20% and housing was 40% and other was 15%.
- •Pure listing
- •No ranking language
- •No grouping
Stronger
Share-focused wording
Housing made up the largest share at 40%, while food and transport together accounted for 45%. Other spending was the smallest slice.
- •Clear hierarchy
- •Combined related idea
- •Natural proportion verbs
For a wider phrase bank, see Task 1 chart vocabulary. For overview wording that stays figure-light, use the overview tips.
Compare two pies over time
Two pies from different years usually need an overview about change: which categories grew as shares, which shrank, and whether the leading category stayed the same. Then give one body paragraph to the larger shifts and another to stable or minor categories. Comparing the same category across years is clearer than finishing the first pie completely before starting the second.
Be careful with language of change. A slice rising from 10 percent to 25 percent means that category became a larger share of the whole. It does not automatically prove that the absolute amount doubled unless the chart also shows totals. Stick to what the percentages show.
- 1Identify the linkConfirm whether the pies show two years, two places, or two groups.
- 2Overview the shiftName the categories that gained or lost share and whether leadership changed.
- 3Detail major moversGive paired percentages for the biggest increases and decreases.
- 4Summarise the restGroup stable or tiny slices so the response stays selective.
Pie chart checklist and common traps
Before you stop writing, confirm selection and honesty. Most pie-chart answers lose marks by listing every slice or inventing causes for a large share.
- Overview names the largest share and the main pattern across pies if there are two
- Small slices are combined instead of listed one by one
- About six to eight figures support the overview
- Category labels match the key
- No causal explanation unless the question asks for it
- Two-pie tasks compare the same categories across years or groups
- Do not treat a share increase as proof that absolute totals doubled
- Do not finish pie one completely before starting pie two
- Do not force fractions that are harder to read than percentages
- Do not ignore a category that changes rank between pies
Pie chart FAQ and next step
Practise with one single pie and one paired-pie task. For each, write the overview first and limit yourself to eight figures. Then check whether small slices were combined cleanly. Review one draft in the Writing Checker.
Must I mention every slice?+
No. Cover the main shares fully and combine minor slices. The overview should still reflect the true balance of the chart.
Can I use fractions instead of percentages?+
Yes, if they remain accurate. Roughly one third or just under a half can vary your style, but do not force awkward fractions.
How should I compare two pies from different years?+
State the main share changes in the overview, then pair the same categories across years in the body paragraphs.
Is it wrong to say a category doubled?+
Only use doubled when the percentage evidence supports that claim. A rise from 10% to 20% is a doubled share, but do not invent absolute totals the chart does not give.
